Abstract

The invention discloses a radial cross-flow moving bed reactor for adsorbing and removing hydrogen sulfide at variable temperature. The reactor comprises a material discharging section, a reaction section and a material discharging section in sequence from top to bottom; due to arrangement of a material discharging structure of the material discharging section, uniform material discharging is guaranteed; due to the arrangement of a gas homogenization baffle at the reaction section, uniform distribution of fed gas in the axial direction and the radial direction is guaranteed, and gas inlet pressure drop is reduced; due to arrangement of an annular material discharging pipe and a funnel material discharging structure at the material discharging section, uniform material discharging is guaranteed, and the phenomenon that the downward moving speed of particles in the central region is higher than that of particles on the wall is avoided. The radial cross-flow moving bed reactor can be used for removing a large amount of hydrogen-sulfide-containing gas with high concentration and has the advantages of uniform material discharging, stable continuous running, low equipment investment and low running cost.

Description

technical field

[0001] The invention relates to the technical field of flue gas comprehensive treatment, in particular to a radial cross-flow moving bed reactor for hydrogen sulfide removal by temperature-swing adsorption. Background technique

[0002] In recent years, when coal, oil and natural gas are used as raw materials to produce ammonia, methanol, methanation gas and other products, high-efficiency catalysts or noble metal catalysts are mostly used. Sulfide poisoning in raw gas is the main reason for catalyst deactivation. Trace amounts of sulfides include sulfide Hydrogen (H 2 S is 0.1ร—10 -6 ) can completely deactivate the catalyst; in addition, hydrogen sulfide (H 2 S) The fuel gas is combusted to generate SO 2 , can form acid rain, pollute the environment, easily corrode metals, block pipes, etc. Therefore, hydrogen sulfide (H2S) is effectively removed from feed gas and fuel gas 2 S) occupies a very important position in the chemical industry.
